Abstract: Apparatus, method and computer program product are provided for digitally processing an encrypted data stream scrambled, for example, according to content scrambling system (CSS) technology. This digital processing insures against communication of clear data within the computer system from a central processing unit (CPU) to any accessible structure, such as memory or a system bus. Descrambling of the (CSS) scrambled data stream occurs within a module executing on the CPU, which is followed by reencryption of the data prior to transfer from the CPU. By so processing the data, integrity of copyrighted material is maintained, while allowing for software descrambling of the CSS encrypted data stream. Various techniques for establishing the encryption/decryption algorithm pair employed are described. Decryption of the re-encrypted data can occur at a receiving software module and/or a receiving hardware device, such as a decoder.

Abstract: This is an accessory for a two wheeled trailer composed basically of three parts for each wheel: a wheelpiece that fastens to the outside of the wheel and that contains in its center a hexrod; a long-handled ratchet that fits in place over the hexrod of the wheelpiece and that contains a long wooden handle which can be taken in hand to rotate the wheel, tied to the trailer frame, or left on the ground to prevent backwards rotation of the wheel in relation to the ground or the trailer frame; and, a mechanical brake that also fits in place over the hexrod of the wheelpiece to control motion and to use in conjunction with the long-handled ratchet for leverage. This invention enables a single individual to easily move a heavily loaded two wheeled trailer over difficult terrain, such as a two wheeled boat trailer on a beach, if one or several techniques are used for leverage and control.

Abstract: Recreation and work-type trailers are difficult to maneuver once detached from the towing vehicle even with the conventional dolley wheel in place. This device includes a horizontal main bar with a pair of plates one at each end being mounted to the underside of the main bar by a bolt and spring loaded to give a limited flexibility thereto. A central socket is pivoted to the upper side of the main bar and receives the stem of the trailer hitch. A handle socket is secured adjacent each end of the main bar also on the upper surface thereof and incline upwardly and outwardly therefrom and selectively receive an elongated handle so that the respective end of the main bar can be elevated by the handle and "walked" forwardly or backwardly or sideways as desired thus maneuvering the trailer readily and easily.

Abstract: A dolly to facilitate the manual moving and positioning of trailers and other vehicles incorporating ratchet mechanisms to provide a high mechanical advantage for moving the vehicles. The ratchet mechanism can be selected to drive in the forward or reverse direction through a ground engaging wheel. A drive disc is mounted for rotation with the ground engaging wheel and is engaged by pawls from drive and holding ratchet mechanisms. The holding ratchet mechanism is mounted on the frame of the device and the drive ratchet mechanism is mounted on a yoke carrying an actuating handle. The mechanisms also permit coasting in the selected direction only. A brake, mounted on the yoke and controlled by a mechanism on the handle, functions to lock the wheel relative to the yoke. This allows the wheel to be rotated relative to the pawls, releasing locked-in-position pawls. Other selected modes may be used to lock the wheel in position to act as a brake or disengage the wheel completely to allow free movement.
